  • LED Chaser Using NE555, CD4017, Infrared Receiver And Photoresistor

    LED Chaser Using NE555, CD4017, Infrared Receiver And Photoresistor

    US $9.95
    14 items sold

    The kit does work normally like a normal LED chaser kit. In addition to its obvious features, it has a photoresistor that allows you to change the speed of the chasing LEDs. In the old LED chaser, the speed is controlled with a variable resistor. In this kit, we have used a photoresistor to work as a variable resistor. As the light falling on the photoresistor changes, the speed of the LEDs also changes.
